Click on the cog icon to open the Device Settings pane, which slides out from the left of the screen; click the icon again to close it. The Device Settings pane lets you make various global settings to the hardware interface, which will remain in force until you change them.
Your Clarett⁺ interface is able to operate at any of six sample rates:
-
44.1 kHz
-
48 kHz
-
88.2 kHz
-
96 kHz
-
176.4 kHz
-
192 kHz
The default sample rate is 48 kHz. Select an alternative sample rate if needed. Note that the optical input is disabled when sample rates of 176.4/192 kHz are in use.
Interconnected digital audio equipment must always use the same reference clock source. Your Clarett⁺ interface is able to synchronise from three sources:
-
Internal – the internally generated reference clock. This is the default selection.
-
S/PDIF – the embedded clock signal in a signal at the S/PDIF IN connector.
-
ADAT – the embedded clock signal in a signal at the OPTICAL IN connector.
Whichever source is selected, the clock signal is available at the Clarett⁺’s WORD CLOCK OUT rear panel BNC socket to allow synchronisation with other digital equipment (only on Clarett⁺ 8Pre).
On the Clarett⁺ 4Pre and 8Pre, you can change which digital input you are using to receive S/PDIF.
By default, the Clarett⁺ will use coaxial S/PDIF. You can change the S/PDIF source to optical, to connect to consumer devices with optical S/PDIF outputs, for example connection to a games console or TV with your Clarett⁺.
It is very convenient to adjust your monitoring volume with a conventional rotary control. Clarett⁺ interfaces have a MONITOR control on the front panel for this purpose. Normally (i.e., by default), this will adjust the level at Monitor Outputs 1 and 2 while also providing Mute and Dim control.
If you are using some of the Clarett⁺’s other outputs for secondary speakers – typically nearfield, though also in LCR or surround setups – you can assign the rotary control, Mute and DIM switches to affect them as well.
The options are:
-
1-2 – Monitor Outputs 1 & 2 (default setting)
-
1-4 – Monitor Outputs 1 & 2 and Line Outputs 3 & 4
-
1-6 – Monitor Outputs 1 & 2 and Line Outputs 3 to 6
-
1-8 – Monitor Outputs 1 & 2 and Line Outputs 3 to 8
-
All – Monitor Outputs 1 & 2 and Line Outputs 3 to 10
-
None – The rotary control, MUTE and DIM switches are disabled; output levels may still be controlled from the software faders.
Note
Assigning outputs 7-8 and 9-10 to monitor control will affect the level of the headphone outputs as they are shared.
In the Output tabs on the Output Routing page, the fader “knob” will be green for the outputs assigned to the hardware rotary control. This means the on-screen fader is inoperative, and you have to adjust the level of those outputs from the front panel. However, the on-screen fader position, plus Mute and Dim status will reflect the hardware control’s operation.
